Low Pass Filter

A Low pass RC filter, again, is a filter circuit composed of a resistor and capacitor which passes through low-frequency signals, while blocking high frequency signals. To create a low pass RC filter, the resistor is placed in series to the input signal and the capacitor is placed in parallel to the input signal, such as shown in the circuit below:

Filter circuits

Capacitor Filter Capacitor Filter. In this filter a capacitor is connected across the load during the rise of the voltage cycle it gets charged and this charge is supplied to the load during the fall in the voltage cycle. This process is repeated for each cycle and thus the repel is reduced across the load. It is shown in the above Figure.

What is Pi Filter?

In pi-filters, the major filtering action is accomplished by the capacitor at input C 1. The residual AC ripples are filtered by inductor coil L and capacitor C 2. The high voltage is obtained at the output of Pi filter, the reason behind this high voltage output is that the entire input voltage appears across the input capacitor C 1 .
